Besides, WQY Micro Hei Mono is a useful font for Simplified Chinese. No other font has such beautiful glyphs for SC. And the font itself should not really matter, a font is just a set of curves, after all. If it is rendered incorrectly, it is a bug in the rendering library, not in the font. A library should accept every font imaginable. >Also, are you using X or Wayland? This shouldn't be able to affect fonts, but X users should not use PGTK. I have both. I am usually using X, but this effect manifests itself on Wayland too. What is wrong about using pgtk with X? GTK works on X.
